Zbrush 4R4

Internal error \VirtualMem.cpp. line 2760 Unable to offline a memory which is offline. Object. Please email us at support2pixologic.com press ok to exit zbrush or cancel to continue.

I’m having this issue. It happens everytime when I append a Tool (for example I´ve appended 2 sphere for eyes and after that when I try to save i get the error’
set to admin + giving folders the right permission did not work… this really sucks.

I’m on a Windows 7 alienware m17x laptop with 8gb ram, i7 3610QM and HD4000/7970M

Please help :frowning:

Is it 4R4 or is it 4R4 P2?

If it is not P2, please update. Simply run “ZUpgrader”, found in your ZBrush 4R4 folder.

Thanks.

Yes it is P2.
Ok I found out the source of the problem, it’s not only a multiple subtool issue as i thought.
What I can do is. Append a tool, save NP
Extract masked. Save NP

what i can NOT do is.
Append a tool, duplicate it and Merge Down with the original tool (or maybe even merge down with anything, havent tested)

This is what corrupts my save, somehow i can not save out a duplicated merged down tool.
I tried to make eyes, so I appended a standard sphere, positioned it, saved NP.
Then I duplicated it ,moved to the other eyesocketand merged down, saved it and got the error.
This is very annoying but at least i know the source of the problem now.

I recreated what you did and the same crash happened to me too.

#5

can you record the session?

#6

Same error on Mac OSX 10.6.8

However I can only replicate it with the Sphere3D. When I do the exact same thing with the polysphere the error doesn’t show up. I tried a couple of other models and it didn’t seem to show up with the error. So on my end it looks like it’s only when the Sphere3d tool is involved.

#7

Wow, It reliefs me that it’s not hardware based… I bought an alienware m17x for school to run programs like 3dsmax, zbrush etc.
Thank god…

#8

I have had a ztool corrupted in a similar way. I DID use the merge-down function before saving. This is a serious problem.

#9

likewise…

is the tool unrecoverable?

#10

I could find no way to recover it.

#11

I was also able to re-create this error using the Sphere3D converted to a polymesh.
This error is really killing me on another project right now, so I have been experiencing
this issue on an actual job, not just sphere testing, and it totally destroys the tool.
Upon trying to re-open the file, I get an ‘out of disk space error’. I hope that there’s a fix
for this in a hurry.

#12

I just found this thread by googling. I found way to save working copy of zbrush project with corrupted subtool. Just clone broken subtool, delete orginal, and append it back to original tool. Now I could save and open file.

#13

Thanks! I cloned and appended together a new tool and it worked. Thanks for saving me hours!!
